Abstract: A novel flow injection chemiluminescent enhancement method for the determination of Fe based on luminol-KIO4 system is developed. The method is simple, rapid and effective to determine Fe(Ⅱ)in the range of 5.0×10-6~5.0×10-9mol/L with a detection limit of 4.4×10-10mol/L.The relative standard deviation is 2.3% for the determination of 2.0×10-7mol/L Fe(Ⅱ) (n=11).The method has been applied to determine the content of iron in milk powder with satisfactory results.

Key words: luminol, potassium periodate, iron (Ⅱ), chemiluminescence enhancement effect, milk powder
